TCPChannels (MQLONG)
This is the maximum number of channels that can be current, or clients that can be connected, that use the TCP/IP transmission protocol.
The value must be in the range 0 through 9999, with a default value of 200. If you specify 0, TCP/IP is not used.
This attribute is supported on z/OS only.
To determine the value of this attribute, use the MQIA_TCP_CHANNELS selector with the MQINQ call.
